8 + 1 channel CWDM module

DescriptionParameterPDF CWDM coarse wavelength division multiplexing optical fiber system can effectively save resources and networking costs, it solves the fiber shortages and multiservice transparent transmission of two issues, mainly used in metro aggregation and access layer of the network can be built in a short time and conduct business. Because CWDM low cost, low power, small size and many other advantages, is a low-price, high-performance transport solution, now widely used in metropolitan transport.
